Anybody have an idea how to map a height field to the inside
of a sphere ? Preferably 360 degrees in all directions.

Any chance Colefax's bend.inc could be used in this regard ?

I think one of the better known heightfield tools / toolsets could map a
heightfield to a sphere and export the result as a POV-mesh. Unfortunately I
don't remember which one (I don't even remember the names of all of them,
but hey, *you* are the linkmaster ;-) Maybe it was HF-Lab?

You love Leveller, right? :) Wasn't there someone who wrote
a plugin for it to map heightfields to objects? I'm not
sure, but...

I suspect you are thinking of John Beale's application which
does this.

There is also a macro which does the same thing which has been
publically released.

Darnit.... yeah...I can do it with my program which I never finished...
It is still a kludge (you need to convert the tgas to oct format first)
but I should be able to patch it to map interiors instead of exteriors
in very little time.  I'll try and get you a exe within 24 hours.

Yes Leveller can do spherical and IIRCC cylindrical HF's
in mesh export now. The thing is it does this externaly
and not internaly. I want the mountains or whatever terrain
pointing inward (inverted).

It there an easy way to convert tga's to .oct ? I'm unfamiliar with
this process.

HF-Lab will do it.  Just load the tga and save as an oct... they are
huge files but I haven't implemented reading tga's yet...

Um, if leveller will do it, why don't you invert the height field and
map it to the exterior?  It should end up the same in the end shouldn't
it?

If you invert the HF image that Leveller uses for height elevation
points all that will happen is that it will be a mirror of itself.
The elevations will still be positive and the terrain will still
be extruded outward from the sphere. Nice try.
